Регулируемый источник питания постоянного тока 50 В 40 А

Adjustable DC voltage stabilized power supply

1. Overview

JK-K series regulated and constant current power supply adopts advanced PWM control technology design, wide input voltage range; adopts advanced switching power supply control technology and components, high efficiency, light weight, energy saving and environmental protection; with stable voltage CV, constant current CC The automatic switching function of the working mode can be used as a constant voltage source or a constant current source. In order to improve the reliability of the power supply, the input undervoltage protection circuit, the output overvoltage protection circuit, and the overheat protection circuit are used. For the convenience of use, this power supply has the function of checking the setting value of constant voltage, constant current and overvoltage protection. In addition, functions such as current remote control, voltage remote control, and switch remote control are optional. In order to adapt to the use of capacitor manufacturers' experienced capacitors, capacitor discharge and pulse aging functions can also be selected. This series of products is an ideal DC regulated power supply, with extremely high stability and reliability, it is widely used in factories, schools, research institutes, laboratories and all other places that require a high-stability DC power supply.
